[Rockhounds] Mantle rock behind Yellowstone's supereruptions extends to Northern California

[Kreigh Tomaszewski]

Victor Camp has spent a lifetime studying volcanic eruptions all over the
world, starting in Saudi Arabia, then Iran, and eventually the Pacific
Northwest. The geology lecturer finds mantle plumes that feed the largest
of these eruptions fascinating, because of their massive size and the
impact they can have on our environment.

Over the past two years, this abiding interest helped him connect the dots
and discover that the mantle source rock <https://phys.org/tags/rock/> that
rises upward from beneath Yellowstone National Park to feed its periodic
supereruptions also spreads out west all the way to Northern California and
Oregon.
